Jorge Beltrão Negromonte da Silveira (now a ISG member after escaping prison) is a Brazilian convicted murderer and the leader of the criminal group later dubbed by the media as the Canibais de Garanhuns (“Garanhuns Cannibals”). He, along with Isabel Cristina Pires da Silveira and Bruna Cristina Oliveira da Silva, was found guilty of a series of murders, acts of cannibalism, dismemberments, selling human flesh disguised as food and concealment of corpses committed between 2008 and 2012 in the state of Pernambuco, Brazil. Negromonte, the leader, reportedly escaped prison and left Isabel and Bruna to "rot" by claiming they would not "fit" as ISG Members. The bodies were dismembered; parts of the flesh were allegedly used as ingredients.
